I would very much like to have a series of different patches rather
than a single big one for this. It allows people to review your
changes in bite size chunks in case they do not have very many hours
of free time available.

I think this needs to be sorted out. Can you look into what registers
are different from coreboot-only to AMI or even AMI-reset-coreboot?

This is also not so nice. Can it be fixed? Who knows a bit about the
azalia stuff? I think there is known good azalia setup in the i945
code. Maybe compare that with what the code for the via does?

Again maybe you can play with VLINK settings in AMI BIOS and compare
northbridge config space values?

This is really close to being completely done! It would be awesome to
have the last issues ironed out, and a series of patches to make
review manageable.
